SSC Selection Post - Matriculation Level - 28th July 2025 - Shift 1 • Reasoning • Q88

Which number from 27, 54, 81, 108, 150 is different from the others?

Show answer & explanation

Correct answer: D

Explanation

27 = 3³

54 = 27 × 2

81 = 3⁴

108 = 27 × 4

150 = 3 × 50 (or 3² × 50), not a clear power of 3/multiple of 27

Note that:

The first four numbers are associated with multiples of 27 or powers of 3, while:

150 is neither a multiple of 27 nor a clear power structure of 3.

Correct answer: 150
